Disconnect circuit being tested from power source. To be safe, disconnect battery ground strap. c. If test calls for an ohms range different than RX1 or X1, set selector switch to that range (like RX10 or X10). d. Connect probes across circuit or item to be measured. The example shows measuring the resistance of one wire in a three-wire cable. e. Read multimeter. 2-12.6 Measuring Dc Voltage a. Set up multimeter. If you are unsure of the voltage to be measured on the vehicle, always start on the highest range. This will protect the meter from damage. 2-10 CAUTION CAUTION
